Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder and systemic disease with multiple comorbidities and largely fragmented clinical care. In this article, we discuss three important components frequently missing from the current ASD standard care routine: oral health, nutrition, and house-call programs. Both ASD centers associated with tertiary-care hospitals and community ASD providers do not regularly offer these services. In this review, we address the benefits of and rationale behind incorporating dental care, nutrition, and house-call programs into ASD management. We also explain why these three services are closely intertwined, with potentially synergistic effects to improve health care outcomes for patients with ASD. Finally, we discuss strategies for service implementation and envision ways in which these three branches of ASD care can be best integrated into a primary care routine.
